proteins that are complementary. (4) – ANS High-fish, poultry, cheese,
eggs, milk, most soybean products complementary-grains and legumes
Define atherosclerosis and identify dietary, lifestyle, blood lipid levels, and
blood pressure measurements that are helpful or harmful for cardiovascular
disease risk. (4) - ANS Definition: the condition in which fatty deposits
called plaque build up on the inner walls of the arteries. leads to
cardiovascular disease, hardening of the arteries, blood clots, etc. it is the
most common form of CVD

saturated and trans fat. high blood triglycerides. hypertension.
Describe BMI and other ways to assess weight, body composition, and fat
distribution, and identify their limitations. Calculate and interpret BMI &

risk from obesity or underweight, calculated by dividing the weight of a
person by the square fo the persons height. found on the table!! (<18.5
